VMIC VMIVME-1110 – VMEbus Digital I/O Board for Reliable Machine and Process Control
The VMIC VMIVME-1110 is a legacy 6U VMEbus I/O board that’s been used for years in industrial control, test stands, and defense systems where deterministic digital signaling really matters. From my experience, it’s the kind of card you keep in service because it’s stable, predictable, and integrates cleanly with existing VME crates without forcing software changes. You might notice that many installed systems use the VMIVME-1110 as the digital interface between a VME controller and field devices—things like interlocks, tool enables, sensors, and simple discrete sequences.
While builds and revisions vary, the VMIVME-1110 typically provides buffered TTL-level digital I/O via the VME backplane with interrupt capability, making it a solid fit for machine control, material handling lines, and retrofit projects where you need to extend the life of a qualified platform. One maintenance lead in a steel mill told me he keeps a spare on the shelf because “it just drops in and runs—no surprises on the bus.”

Key Features
- VMEbus compatibility – Fits standard 6U VME backplanes in mixed-vendor crates for straightforward replacement or expansion.
- Buffered TTL digital I/O – Commonly used for discrete machine signals; predictable 5 V logic levels simplify wiring with legacy harnesses.
- Interrupt support – In many cases, the board supports VME interrupts for time-critical events and efficient CPU utilization.
- Stable, field-proven hardware – Long service history in factories, energy, and defense means fewer surprises in validation.
- Service-friendly – Typically front-accessible connectors and straightforward loopback testing reduce downtime during maintenance.
- Lifecycle extension – Ideal for sustaining qualified systems where software and I/O maps must remain unchanged.

Related or Supporting Products
- VMIVME-1100 series (TTL digital I/O) – Similar family boards with different channel counts or buffering; useful if you need pin-compatible variants.
- VMIVME-1160 / 1170 (isolated digital I/O) – If isolation to field wiring is important, these variants typically add opto or relay isolation.
- DIN-rail terminal breakout boards (50/64-pin) – Screw-terminal adapters and ribbon assemblies for quick panel wiring and field service.
- VME single board computers (e.g., PPC/Intel-based) – Controller cards to pair with the VMIVME-1110 for closed-loop machine control and data logging.
Installation & Maintenance
- Cabinet & environment – Install in a VME 6U chassis with adequate forced-air cooling. Keep ambient within 0–55 °C and avoid corrosive atmospheres.
- Wiring – Use shielded cable for longer runs. Maintain proper return/ground for TTL signals to avoid false triggering. Label harnesses to match channel maps.
- ESD handling – Treat as an ESD-sensitive assembly. Power down and discharge before insertion or removal from the VME crate.
- Configuration – Verify address settings and, where applicable, jumper/strap options for I/O direction and interrupt level prior to commissioning.
- Routine checks – Inspect connectors quarterly; re-seat during scheduled downtime. Light dusting with dry air helps keep thermal performance stable.
- Functional test – A quick loopback or lamp-test procedure on a terminal breakout panel typically confirms channel health in minutes.
